Simon Urli indeed, Message stream will not be there anymore, but there still is a "network" feature in XWiki, where a user can follow other users in order to get notifications from their activity. This network feature alows to see who you follow (in your user profile) but doesn't allow to see who's following you, as this ticket says. Did you by any chance create the corresponding network feature ticket? Can we link it from here, for completude?
